Learning Goals by Measurement Topic (MT)
Students will be able to . . .
Number and
Operations-Fractions
Number and Operations in
Base Ten
•
•
use equations ( number sentences with an equal sign), rectangular arrays, or area
models to divide a 4-digit number by a 2-digit number.
use estimation strategies based on place value, properties of operations, and the
relationship between multiplication and division to solve division problems.
reason about the relationships among dividends, divisors, and quotients.
•
solve problems involving four operations (+, -, ×, ÷).
•
use equivalent fractions as a strategy to add and subtract fractions with unlike
denominators.
solve word problems involving addition and subtraction of fractions with unlike
denominators.
apply understanding of factors and multiples to generate equivalent fractions and add
fractions with unlike denominators.
reason about relationships among numerators and denominators to add fractions with
unlike denominators.

Thinking and Academic Success Skills (TASS)
Taking
Intellectual Risk
Flexibility
It is . . .
being open and
•
responsive to new
and diverse ideas and •
strategies and
moving freely among
them.
accepting uncertainty •
or challenging the
•
norm to reach a
•
goal.
In mathematics, students will . . .
make the connection that knowledge of equivalent fractions helps
adding and subtracting fractions with unlike denominators easier.
use a variety of methods to add and subtract fractions with unlike
denominators.
generate multiple ways to find solutions to word problems.
make adjustments to thinking when problem solving.
recognize that….
o mistakes can help one learn.
o skillful students ask for help and feedback.
o it is okay to not understand everything the first time around.
o everyone is capable of high achievement.

In school, your child will . . .
•
At home, your child can . . .
use area models and equations to solve a multi-digit division
problem (4-digit number by 2-digit number).
•
practice solving multiplication and division problems using mental math to
develop skills to solve more difficult problems.
Example: 4 x 8 = 32
40 x 80 = 3,200
3,200 ÷ 40 = 80
•
•
estimate the quotient using knowledge of place value.
estimate and solve 4-digit by 2-digit division problems using an area model
to show the relationship between multiplication and division.

Number and Operations in Base Ten
Example: Use a ten-thousand grid to solve 1,786 ÷ 40 = 44 𝟒𝟒
40 x 40=
1,600
40 x 40=
1,600
40 x 4= 160
Remainder 26
Note: This is a portion of a ten-thousand grid.
